2 * HA-Proxy : High Availability-enabled HTTP/TCP proxy

10 * Please refer to RFC2068 or RFC2616 for informations about HTTP protocol, and
11 * RFC2965 for informations about cookies usage. More generally, the IETF HTTP
12 * Working Group's web site should be consulted for protocol related changes :
13 *
14 * http://ftp.ics.uci.edu/pub/ietf/http/
15 *
16 * Pending bugs (may be not fixed because never reproduced) :
17 * - solaris only : sometimes, an HTTP proxy with only a dispatch address causes
18 * the proxy to terminate (no core) if the client breaks the connection during
19 * the response. Seen on 1.1.8pre4, but never reproduced. May not be related to
20 * the snprintf() bug since requests were simple (GET / HTTP/1.0), but may be
21 * related to missing setsid() (fixed in 1.1.15)
22 * - a proxy with an invalid config will prevent the startup even if disabled.
23 *
24 * ChangeLog has moved to the CHANGELOG file.
25 *

890 * It's a bit tricky. If memmax is not set, maxconn defaults to
891 * DEFAULT_MAXCONN and maxsslconn defaults to DEFAULT_MAXSSLCONN.
892 *
893 * If memmax is set, then it depends on which values are set. If
894 * maxsslconn is set, we use memmax to determine how many cleartext
895 * connections may be added, and set maxconn to the sum of the two.
896 * If maxconn is set and not maxsslconn, maxsslconn is computed from
897 * the remaining amount of memory between memmax and the cleartext
898 * connections. If neither are set, then it is considered that all
899 * connections are SSL-capable, and maxconn is computed based on this,
900 * then maxsslconn accordingly. We need to know if SSL is used on the
901 * frontends, backends, or both, because when it's used on both sides,
902 * we need twice the value for maxsslconn, but we only count the
903 * handshake once since it is not performed on the two sides at the
904 * same time (frontend-side is terminated before backend-side begins).
905 * The SSL stack is supposed to have filled ssl_session_cost and
Willy Tarreau474b96a2015-01-28 19:03:21 +0100906 * ssl_handshake_cost during its initialization. In any case, if
907 * SYSTEM_MAXCONN is set, we still enforce it as an upper limit for
908 * maxconn in order to protect the system.
